To all 'whom t may concern.'

Be itknown that I, LAMONT H-SrnoUD, a citizen of the United States, residing at Sheridamin the county of Sheridan .and

State of Wyoming, have invented 'certain new and useful Improvements in Station- Indicators; and l do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to makeand use'the same.

My invention relates to improvements in station indicators adapted for use in cars, An important object of this invention is tol-provide novel means for automatically starting and stopping the indicator to display the proper station upon approaching the station. -V Y A further object of the invention is to provide an indicator having novel meansfor controlling the indicator cloth from one roll to another whereby all slack is prevented inthe indicator cloth. Y Y

A further object of` the provide a novel actuating conveyer. ,c Y

A further object of the invention is to provide an indicator which is simple to invention is to means for the install, automaticv in,v its operation, and highly reliable'in use. Y c,

Fig. 7 is a vertical transverse section taken on line 7-7 of Fig. 5.

In the drawings, wherein for the purpose of 'illustration is shownthe preferred em bodiment ofv I ny invention, the numeral 10 generally indicates a car having a running gear 11. Wheels 12. are included in the running gear and are mounted on tracks 13. A housing 14 is carried by the running gear 11'and receives *an actuator rod 15. The

l actuator rod 15 is movable vertically and is Vactuator rod 15 for pushing the same upwardly. rlhe trip block 17 has connection at its lower end with a bell crank 18. The bell crank 18 has connection with horizontal and vertical links 19 and 20 respectively. An operating lever'21 whichmay be arranged at any point with relation to the trip lock 17 is connected to the vertical links 20 by a suitable connecting element 22. The lever 21 is adapted for positioning the trip lock 17 in an operative or non-operative position.

rlhe actuator rod 15 has connection with a bell crank 23 pivotally secured as at 24 within the housing 14. VA vertically disposed arm 25 is provided with a laterally extending pin 26connected to the bell crank 23 by a link 27. A shaft 28l is vprovidedV with an extensible slip joint 29. A universal -joint 30 connects the shaft 28 to the verti- 'cal arm 25. A vertical shaft 31 is connected to the shaft V28 by a universal joint 32.

The upper end ofthe shaft 31 extends into an indicator casing 33. An electric motor 34 is arranged within the casing 33 and is provided withfa pinion 35 meshing with a relatively large gear 36. The relatively` large gear 36 is mounted on a transverse shaft 37 which also carries a pulley 38.A The electric motor has connection with a V*suitable source of electrical energy 39 through wires y 40.

As clearly shown in Figs. 1 and 4, a pul- Vley41 is carried-by a frame 42 disposed within the casing and has connection with the pulley 38 by a belt 43. The belt 43 may be provided with a twist as indicated in dotted lines in Fig. 1 for reversing the direction of rotation of thepulley 41. Spools 44 and 45 are disposed within the casing and receive and dispense an indicator cloth The indicator cloth 45 is connected at its ends to the spools 44 and45 and passes over a pair of rollers 46 and 47. The rollers 46 and 47 are carried by the frames 42 and are disposed rearwardly of the sight opening 48. The roller 47 is provided with cog Vwheels 49 engaging marginal apertures 50 in the indicator cloth 45. `The lower spool or roller 47 has connection with the pulley 41 and is adapted for positively driving the Vindicator "cloth a predetermined portion of its length at each operation of the electric motor-regardless of the amount of cloth on `either of the spools 44 and 45.

No rotate the spools 44 and 45 at speeds to insure the equalA dispensing and receiving of cloth, I have provided an equalizer 51. The equalizerv 51 includes a pair of spools l52 which have rigid connection with the spools 44 and 45. An equalizer tape 53 is adapted to be wound about the spools 52 as is the cloth 45 wound about the rollers 44 and 45. An equalizer belt 54 of an elastic material is disposed about the spool 52 and the equalizing tape 53 wherebythe spools 44V and 45 are caused to rotate in syncro-V nism.

As clearly illustrated in Figs. 1 and 3, a pair of contacts-55' and 56 are interposed in one ofthe wires of the electric circuit. The

contact 56 has rigid lconnection with a brake y 57 adapted i to engage the equalizer 51 for' stopping the operation of the indicator cloth f l upon the completion of one rotation of the operating gear 36. The integral elements 56and 57 are pivotally supported bythe the same is normally spaced from the contact 55. VThe upper end of :the shaft 31 is provided with an oliset engagingy the master 4arm 59 when the same is in a horizontal position. Upon the rotation of the shaft 31 in the direction of the arrow in F ig. 1 the vmaster arm 59 is thrown out of engagement with the contact 56 thereby closing the circuit and starting the'motor. The gear 36 isV caused to partake of a complete i revolutionl and carries with it' the master arm 59 which uponcompleting the'revolutionagain engages the contact 56 and breaks thecircuit. Upon the disengagement ofthe master arm with the contact 56,the brake 57 is'brought out Vof engagement with the Y. equalizer and the movable contact intouengagement with the stationary contact by a coil spring 66. One Vcomplete revolution of the gear 36 causes the name of the next station to appear on the indicator cloth.AV

If desired, a bell 67 may be connected to the contacts 55 and56 by wires 68. A suitable source of electrical energy 69 may be employed for the bell 67. In the use of my invention, it will be apparent that the trip rod 15 iscaused to move upwardly by en-v gagement with the trip block`17, withthe result that theshaft 31 is caused to rotate in the direction indicated by the arrow and thereby cause the master larm 59 to be re leased from engagement with the contact 56.

As described, the contact 56 engages the contact 55 upon being released and thereby closes the circuit which causes the-motor 34 to operate. lThe operation of the motor 34 rotates the pulley'41 which positivelyV 'rotates the indicator cloth the necessary distance to present the name of the next station; The equalizer 51serves to rotate the spools 44 and 45 to transfer the indicatorY cloth 45 from one to the other without any slack.

While I have shown anddescribed thepreerred embodiment of my invention,` itis understood that I may make such minor` changes in arrangement and construction of parts, as will remain within the spiritof the' invention and thescope of the appended claims. y
